The spiral bevel gear used in medical machinery is a special gear transmission device commonly used in surgical instruments, medical robots and other equipment. Spiral bevel gears are composed of a spiral gear and a bevel gear, and their transmission function is achieved through their meshing.
Spiral bevel gears have the following characteristics:
1. High transmission efficiency: The tooth surface of the spiral bevel gear is spiral, which can achieve a larger contact area and improve transmission efficiency.
2. Smooth operation: When the tooth surfaces of the spiral bevel gear mesh, the contact points of the gear tooth surfaces gradually move from the axial direction, reducing the impact and noise of the tooth surfaces and making the transmission more stable.
3. Small axial force: When the tooth surfaces of the spiral bevel gear mesh, the axial force is small, which reduces the load on the bearing and extends the life of the bearing.
4. Good self-locking performance: Spiral bevel gears have good self-locking performance and can prevent the transmission device from reversing.
Spiral bevel gears for medical machinery are usually made of high-strength, wear-resistant materials to ensure their reliability and durability. In addition, spiral bevel gears have high precision requirements and require precision processing and matching to ensure the accuracy and stability of transmission.
